Hi Don,
Set your scanning program to 100dpi. The Approvals program can take upto about 1.2MB. It will resize to optimize the display, but if you go much over the 1.2MB it runs out of RAM(memory) on the server to manipulate the image in.

Don: If you don't want to re-scan, you can also resize your images with most photo programs.
I use Irfanview ( a free program ), and it is a two click affair...resize (enter a percent of original) and sharpen (set it just once) at the same time...one click, then then save as.
Voila!

Hi Don;
In some programs (I use Corel PhotoPaint 8), it is called "re-sample" not scale. In some
programs 'scale' changes the size but not the number of pixels. When I scan, images for
approvals I use the following settings:
Brightness Value: 10
Contrast Value: 20
Highlight Value: 255
Shadow Value: 0
Midtone Value: 1.70
Image Mode: true Color RGB
Image Resolution: 400 DPI (pixels)
Moire Reduction: No Descreen
Image Sharpen/Blur: No Filter
Image Output Size: 100%
File Name: TMPxxx
File Format: .jpeg
Image Quality: Excellant (100%)
These settings are for a UMAX Vista-scan flat bed scanner. Unlike Hewlett Packard, Umax
is superior because that is all they make is scanners. Hewlett Packard doesn't make any-
thing. Like Sears & Roebuck they spec everything out and somebody else makes it, and
brand labels it for them. Hewlett Packard 'sells' Oscilloscopes and other test equipment,
and medical ECG monitors. Their monitors were also inferior as well, as I was a tech at
SpaceLabs who made the most state of the art ECG monitors. Also avoid their computers
they are totally junk!
Those settings may not make sense on your scanner, but the most important one is
400dpi @ 100%. Then if you need to edit the image or tweak it in any way you can better
see how the results will look. This is the best time to use 'sharpen' (focus) and
'Brightness/Contrast', or 'Hue/Saturation' adjustments.
After the image is exactly the way you want it to look, use 're-sample' to reduce down to
940 pixels wide. Images wider than 940 pixels, and the buyer will have to scroll from
side-to-side. I hate scrolling at all. I have a wheel mouse so vertical scrolling is not too
bad. Horizontal scrolling, I'll just go to a different book.
Then after re-sampling the image do a "save-as" and use 20% compression. All of my
images are under 400Kb, and in .JPEG format.
SOR's software tends to darken the image a good bit. So before loading 24 pages of
stamps, load one and open it and see if it is too dark. If it is then go back and adjust
your brightness in the image editing software. Once you find the magic numbers, jot
them down and use for all your pages and then you won't have to edit all 24 of them.
If I've only confused you, or you have additional questions, don't hesitate to ask. You
are welcome to peek at my two books, which I'll be retiring soon, if you want to see my
results. I look forward to seeing what you have to sell on here.

I went to the web site and to down load the program you have to accept a new tool bar. It says you can remove the tool bar afterwards. I would not go to all that work and risk finding out it leaves other items on my computer.
So as good as you say there has to be a better way to down load that program.

As rrraphy said, check the size issue.
I know most people live by Ifranview, although I disagree with the 100dpi number (I personally think you can't do anything less than 300dpi.. but don't need 600dpi unless you really want a high-size file).
And ALWAYS ALWAYS ALWAYS export your files to .jpg format in whatever software you use (I know on GIMP the original scans will be about a 1.2M file, and exporting will drop them to about 92-100K usually - but it took forever (2014) for someone to write up a good TWAIN/Scanner tool for the software.). PNGS, GIFs, XCF's, etc. are HUGE in comparison to .jpgs

I use irfanview and NEVER resize using dpi settings. I always resize using pixels (max 900 width and 1200 height works perfectly on the SOR site). Like the previous post, I do not like the resolution with 100dpi, so I scan with 200dpi standard and, when I want a little better quality, 300dpi. I am too impatient to use higher resolution settings as the scans take too long.

I disagree with DeSaintFan.
I normally scan at stamps, covers, and postcards at 300dpi and 200% or 300% of actual size, which allows me to create large, clear images. I use (Pixelmator, a powerful and less-expensive alternative to Photoshop) to resize and compress those large images for the web.
However, I sometimes use 72dpi to create images that are for temporary use, such as this particular post. Here is an image of a Netherlands stamp scanned at 72dpi and 300%; the dimensions are 410X308 pixels, and the image takes up 33 KB of memory :
Looks fine to me! Now here's the same stamp scanned at 300dpi and 300% of actual size, then resized and compressed for the web:
The main difference is that it took a lot longer to scan and to produce a usable image. Differences in brightness and contrast result from my eyeballing the results rather than duplicating brightness and contrast settings. My bottom line: High dpi produces very large, detailed images which have to be compressed and resized for use on the web. I can quickly produce clear images using 72 dpi for the initial scan, and not have be bothered with resizing.
Finally, the biggest advantage of scanning at 300dpi or greater and size setting larger than the original is the detail that can be captured. Here's a detail of the Dutch stamp, cropped from the original 300 dpi/300% image, then compressed for the web.

I am using an HP scanner to develop pages for approvals. The scans come out at 1-2 megs and the maximum allowed by SOR is 850K. Is there a way to get the scanner to resize or do I need some photo program to do it?
Thanks.
