Image size guidance needed

[Cherchez]

Hi all,
I'm using Phoca Gallery very successfully on a website. It's fantastic! But as I'm managing hundreds of photos - soon to be a few thousand - I need some guidance on size of jpgs that I upload. I show the photos in a slideshow - you can see the type of thing at http://www.midsurreylink.org/the-photo- ... ategory/20 and whilst I know that the thumbnails are created up front, it looks to me as if the images are resized on the fly - so I'm mostly concerned about server loading if the jpgs are large and I get a lot of visitors. I have plenty of space on my server.

My question is: Should I resize photos (e.g. using PixResizer) before uploading them or should I let Phoca Gallery do the resizing for me?

I also have thousands of photos on my website. As a rule I never upload pictures (much) larger than the largest format that is shown (640x480 depending on your settings in parameters). That saves space and probably also processing time on the server and you have more control over the quality compared to what happens with an automatic resize on the server.

Hi, thumbnails are not crated online. Thumbnails are created by uploading (frontend) or adding into gallery (admin). So this depends on your GD. Of course if the images are smaller, then you save the memory, GD, cpu while creating. But creating happens only one time. After it, the thumbnails are created and no more are crated while accessing and viewing by users.
