The image must not be bigger than 700 pixels high and 500 pixels wide. It also musn't be bigger than 200,000 Bytes (195 KBytes).

Otherwise the contribution process will resize the image.


DPI does not matter.

If you scan images for your personal database at a quality that are higher than 100 DPI, you may still submit them. If accepted, they will automatically be downsized for inclusion in the main database.

DJ Doena is right. Even though the text you have quoted is part of the rules or web site (I can't remember), this text is incorrect for different physical cover sizes. All that matters is the number of pixels (width and height) and bytes.

It's in the Rules.

Also, I don't believe it is incorrect. I've got a cover scan up right now that was scanned & uploaded at 300DPI. I've just downloaded submitted version from the contribution system & the DPI of this version has been reduced as stated in the quoted rule.

Of course your scan will be scaled down. A cover of normal DVD cover size scanned with 300 dpi is larger than 500 by 700 pixels. But the cover of your favourite matchbox scanned at 300 dpi will be smaller than 500 by 700 pixels and therefore will not be rescaled.

DPI & image dimensions aren't tied together. You can decrease one, without decreasing the other & vice versa.

Edit: I have two images, an original at 1663x2314 at 300DPI. I also have a copy of that file also at 300DPI with dimensions of 500x696 instead. The latter was edited in PSP reducing the dimensions but retaining the same DPI.

Dpi, physical image size (cm/inches), and pixel size are tied together. You can't change one without changing at least another.

Yes, but you have changed the physical image size. When you print it, the size of the print out will be different.

I never mentioned anything about printing.

Anyway, regardless of all of that, the original statement regarding DPI not mattering isn't correct. There won't be any images in the online database with a DPI over 100.

I scan mine at 600dpi (the optical resolution of my scanner)

Through Photoshop I edit and correct scratches, mars and dust.

I then adjust resolution from 600 to 300 filtering bicubic smoother (to eliminate scanner lines)

I then adjust resolution down to 150 filtering again Bicubic smoother

I then adjust resolution to 100 and adjust image size (already close, just a tweak)

When I save as jpeg, i then adjust  compression to the largest setting to keep it below 170,000 bytes

Then I contribute that image. I keep the 600dpi image stored on separate drive.  Since I have started doing that (aside from some yellow problems on certain scans) I haven't had an issue.

Why not the full 200,000 ?

At one time, I was told (whether right or wrong) that there was a limit around that mark.  I never changed. (and truthfully, even if I compressed a little less, it wouldn't make much difference.

Just a personal thing
