Photo display problems

I have uploaded some photos to my web site. The photos are in color. I noticed that some photos, for whatever reason, do not display properly and either get pixelated or get dark bands over them. I can correct this sometimes by making the photo black and white. Is there some way of optimizing photos when displaying on the web?

I can only see irregularities on two of the pictures: the '66 Mustang Convertible and the late '40s Jaguar. Both of which are black and white. The other four I see perfectly fine, and three of those are in color.

The mustang has a horizontal line about 125 pixels down from the left edge all the way right to the purple/yellow dog. There's also a vertical line on the bottom about 15px from the left side.

The Jaguar seems to be missing the bottom 60% of the image. It's all yellow.

I'm no photo expert and only jumped in out of curiosity, but it looks like the images you uploaded are corrupted. It may have happened when the pictures were taken, or when you shrunk them down, or when it was uploaded to the web server. Do the originals have any issues like that? If not, you should retry shrinking them down and uploading them to the site. Hopefully you still have the originals.

P.S. Thanks for sending me a reminder PM. =) I had a reply for you 2 days ago, but my Internet cut out due to storms and forgot about this thread yesterday.

Xps86,

The originals have no issues. Some of the pictures are black and white because they too were giving me problems and I had to convert them to black and white; otherwise, they were coming out like the Jaguar. The Jaguar is confusing, because even converting it to black and white doesn't help. I experienced this before with photos from my digital camera. These photos were taken with my cell phone. I use a program that came with my digital camera to convert the pictures to a smaller size. It seems that sometimes, for whatever reason, the pictures do not upload properly and display poorly. I have a DSL connection, which I think should be fast enough to transfer photos without corruption. The photos are all around 60K in size.

One other thing I completely forgot about. The pictures were uploaded using a "wireless" connection. Maybe in transmission some bits got corrupted. But, I also remember transmitting photos with a "wired" connection and still some photos had problems. My ISP uses UNIX servers; maybe there's something you can use to optimize pictures which will be put on UNIX servers.

Data corruption can occur even from using a wired connection, though it's more probable to occur on a wireless one. If the originals aren't flawed, I would start from the beginning and try again. Make a copy of the originals, adjust the copies to your liking (dimensions and whatnot), then re-upload to the web server. Using a Unix server wouldn't matter and 4/6 of the photos display just fine.
