RE-saving jpg photos

[Android]

I got my last roll of film from the developer and there's a couple of photo's I'd like to use; however, they're in jpg format and need cropping. Has anybody got any experience with manipulating a jpg photo in any brand of editor and saving it without degrading the quality? They're photos of art, so hi-res potential is important to my customer.
I asked them at the photo shop if they could save my photos on CD-ROM in bmp format and they said 'no'. Is that true? Or do they just think they can't? I would think that they would have some kind of option on their machine to switch formats!
Would the best thing to do be to scan the photos myself and save the 12 dollar CD-ROM option?
Any answers/comments appreciated!

The best file to save to is TIFF, you will have to search for a good developer to transform negs to TIFF on a cd. It can be done as BMP but you will lose image quality and the file size will be way to big.

JPG is the next file format to go for.

If you are looking to get images developed from a CD to photographic paper then I would suggest you first find a place that does. Most do but not with any extras. Most will only offer a standard 8*6 print or next size up. Find out what pixel dimesions they will do for you as well.

If you are serious about it I would suggest one of two things. Buy a spanking brand new fuji finepix S2 digital camera (images will goto 4 foot * 6 foot beofre losing image definition, meoooow) for about 3000 dollars or invest in a negative scanner to store your pics. Neg scanners come in at about 700 dollars for a very good one. Dont flatbed scan them, waste of time.

Any questions in this area fire away...

by the way to store a SLR 35mm camera shot on BMP at highest res so you dont lose the image the file size will exceed 50 meg easily... Save as JPG or TIFF at around 30 meg for the same high quality.

I'm happy with the prints I get, they just have to be cropped to put on the web. Re-saving the jpg makes it less 'snappy'. I get better results scanning the photos. Guess I'll save the twelve bucks per cd.
After 250 rolls of film, I can buy the camera. ;)

I use Irfranview, it is pretty good to do stuff like that. I don't notice too much loss. I crop and resize then I sharpen and it looks fine.
