Sprite looks washed out on site

[eldomtom2]

I originally posted this on the Ripping Help forum, but realised it would be better placed here. I hope reposting it here isn't against the rules.

I am ripping the sprites from Chris Sawyer's Locomotion. When I rip them, the image looks normal.
   
But when I upload it to the Spriters Resource, it becomes washed out for some reason.

Because it gets resized to fit the screen. Click on the sheet and it will show up on its original size.

No, it happens even when I click on the sheet to display the full image. If I download that image though the colours are restored in the downloaded image.

Probably some kind of gamma or color profile information stored in the image that makes it appear brighter in browsers. Check to make sure they're set to the defaults when saving the image.

I have no idea how I'd adjust those things, though. I've attached the file I'm trying to upload in case anyone can spot the problem.

Yeah, it's exactly like I thought then. Opening it up in Photoshop gives me the following message:

Embedded Profile Mismatch

The document "2EPB.png" has an embedded color profile that does not match the current RGB working space. The current RGB color management policy is to discard profiles that do not match the working space.

Embedded: opRGB
Working: Monitor RGB - sRGB IEC61966-2.1

Not sure which program you used to sheet it in the first place, but a quick way to fix that without fiddling with your program's settings would be to download Noesis, and have it convert your PNG into PNG (this will re-encode it without the color profile information attached to it), and even though it'll revert the output PNG back into a 32-bit image instead of the color-indexed one, it shouldn't look washed-out if you were to upload that.

Thank you, that actually worked. Now I can put this behind me and get to the actual work of ripping the sprites.
