Someone posted a link to a free program that would batch optimize JPGs and remove exif information. Of course, I can't find the thread now. Thanks.

Have you tried the "search" feature and searching for a specific uncommon word that was in the thread you are referring to? If the word "Optimize" was used, you could search that and pull up links to threads that contain that word.

It is called "Interactive JPEG Optimizer" I had to google it to find the download site again, it's not from the exact address that someone posted. But, it is the same same program. http://www.fullyregistered.com/

That's it, Aishai. Thanks. Here's the thread. http://www.renderosity.com/messages.ez?Form.ShowMessage=2267867 Acadia, I tried searching with several words and combinations, but I didn't hit the right one.

That does an amazing job of compressing files, but it still leaves the EXIF information, which, in the images I want to fix, is Photoshop stuff that causes problems with another program I use. Irfanfiew has a lossless JPG conversion, but it only does one image at a time.

I don't really know what you are talking about.. but if you are trying to do a batch conversion of files, you can do batch conversion in Paint Shop Pro. The other day I converted a batch of .jpg files to .bmp.

Many image programs write extra settings and more information into the file. Photoshop does, and digital cameras can, too. I figured out that I already have a program that will almost do what I want, Thumbnailer from http://www.smalleranimals.com/

And here I thought a .jpg was a .jpg was a .jpg. What type of "extra settings and information" are you talking about? I know when you save an animated .gif you can add information into the window such as who created it, but so far as .jpg images are concerned, all I know is that you can adjust the amount of compression.

Here's the header stripping program, I think, posted by xonocostle in this thread: http://www.renderosity.com/messages.ez?Form.ShowMessage=2353291 JPG Cleaner v2.6 - go to Programs at the link.

Another in the long list of things I've downloaded and haven't used yet..;)

That's it, EnglishBob! Thank you. Acadia, the extra stuff can be camera settings that were used when the picture was taken, Photoshop can put a thumbnail image inside the file, there are programs that allow you to put comments in, and there are even programs that encript text into image files to "hide" the information. Secret messages. That's it, EnglishBob! Thank you. Acadia, Here is a page with another header extractstrip program that has a list of what the extra information can be. http://www.sentex.net/~mwandel/jhead/

I use JPG Cleaner too. The main cuplrit is the photoshop preview image (the one you see in the Open dialog when you click on a file). But to be honest, the best way to avoid it is to use Save for web. I never use normal save for my texs, alwys Save for web at maximum (100) quality. mac

maclean, I'm glad that at least one person knows about the extra info that Photoshop puts in. I'm looking at this to work on textures from many other merchants that don't know yet. It would be great if the stores would do something to educate, but most of them probably don't know about it, either. I posted a thread about jpg file overhead in the DAZ forums a while back, but didn't get much response.

wyrwulf, I spent days trying out every combination of texture-saving I could think of, rendering the results and comparing them. I had folders full of test renders. In the end, I settled on what I mentioned above - PS Save for web at maximum quality. I'm always amazed how some merchants can make 4096x4096 texs and save them at low-quality settings. The ONLY way to go is maximum quality, then decide on the size you need. A best-quality 1024 tex will beat a mediocre 2048 any time. In addition, I stick to 'power of 2' sizes, and always tend to use square tex formats. If you offer poser an 1800x1800 tex, it'll treat it as 2048x2048, so in-between sizes aren't a good idea. This applies to most 3d apps. And square formats are more easily read. mac

I guess that everyone has to figure out the best settings for themselves and what they make. There wouldn't be any formula that would be one size fits all. I know that people have been talking about the "power of 2" and square maps for Poser for years. I can only imagine how hard it is to balance size and quality for texture maps.

I posted the link to Interactive JPEG Optimizer though I don't know about any batch capabilities. If you work/play with digital photos you should check out the free utilities from MediaChance. Their ColorCastFX is great. and the CleanSkinFX is good for cleaning up skin textures in digital photos and even works for Poser images which I suppose are the ultimate digital photos :-) Left-Before Right->After

I use irfanview and the gimp both are free, irfanview will get rid of the extra information and batch stuff. The gimp makes my jpg's smaller. http://www.irfanview.com http://gimp-win.sourceforge.net
