Is there a recommended image size for imaguev2 pictures.

I have noticed that our site seems much slower than others I check out in the showcase forum. I'm wondering if that is because we have pictures that average around 800k - 1200k.

What should we be aiming for in file size and dimensions?

Is there a good way to resize without losing quality. I do have photoshop and lightroom.

Thanks

You have to think about what size screens your viewers might have.

Off the top of my head, I'd say your images are way too big.

I use 1024 on the longer size just in case someone has a large screen and they use full screen view. My images are 100 - 200 k in size.

We use gd, almost built-in php library, usually php memory limit is set high enough to process something that fits most of the screens.

Puctures directly from camera will be too big for almost every server and screen anyway.

On sites like flickr they do all the resizing with external app, something most of the people won't be able to do on their sites anyway.

Resizing and compressing images for the web(including Imagevue) is a fine tuned balance between quality, size and compression.

Normally, I would recommend something in between 800px - 1280px long side. I usually set JPG quality at around 80-85 ... It provides relatively high quality, but still reduces filesize without creating compression artifacts that are easily visible. In this day and age where 17" LCD monitors with 1280x1024 resolution are becoming standard, I feel images at 1024x768 is a good balance.

I believe you should be able to get 1024px images down to filesize 300kb with respectable compression. 800-1200k sounds like overkill ... What dimensions are those images?

Photoshop has good JPG compression if you choose "Save for Web..."

Bear in mind that you will lose the exif data if you "save for web"

Thanks for the tip - I wasn't aware of that.

I have however been told earlier that the JPG compression algorithm of "save as..." is not as good as "save for web..." in Photoshop. Perhaps that has been fixed in latest releases.

Personally, I use irfanview www.irfanview.com to batch resize photos. It's a small free program, that can batch resize photos, and it retains EXIF data.
