Hi guys!

I was wondering on how to bring down the size of my site, but still, keeping all my photos. So, please let me know if some-how I could do the following when uploading a photo:

1. upload the full photo.
2. resize the photo to the first matching "default" resize combination.
3. keep ONLY the resized file.
4. review the permission to see the original size of the photo.

I belive I speak for a lot of people out there when the usual visitors of the site will not want to see a 2200x1400 version of the photo, but will be happy with a fast loading, smaller picture.

Not to mention that the space used by the photo album will be reduced 75% :)

Please do not mention to resize the pics BEFORE uploading ;)

All the best!
Cristian.

resize before upload. it's easy, it's just a few clicks (irfanview -> batch resize hundreds / htousands of photos at once).

the G2 sizelimit module resizes higher resolution / large filesize images on upload to something more adequate and purges the originally uploaded photo.

Thanks a lot for your quick reply.
I am planning to use the batch resize feature of the irfanview/acdsee when
migrating from my legacy system to G2, but usualy, I will use the sizelimit
module for day-to-day uploads :)

Thanks again!
Cristian.

thanks for the info on irfanview and the sizelimit module.

does anybody have any experience on the resizing method that gives the best quality resized images (I know Photoshop is best, but no batch function):
- I currently use my local test install of G2 and GD (set at 95%) to resize images (I copy and rename the dat files from the cache directory ... )
- irfanview -- what technology is used for image resize ? (i'm a bit worried when I see the pictures the authors put on their website http://www.irfanview.com/main_about.htm ;-) )
- sizelimit module (I imagine this module also uses GD (or other installed graph binary)?)

thanks for any advice.

Seriously, I have seen very little visual difference between Irfanview, Photoshop, Gimp, PaintShop, PhotoImpact and G2 (using ImageMagick or NetPBM) for resizing pics. Yes, Photoshop may be best because is leaves in more data, but it is the worst for saving to web-friendly images. The visual image quality is imposible to notice on a computer screen.

However, I would use something else like ImageMagick or NetPBM with G2 as GD isn't the best in resources or quality IMO.

Thanks.
I think my hosting provider only gives access to GD. How can I test that IM or NetPBM are installed and operational on their server? Is it somewhere in the phpinfo output?

photoshop has batch functions of course. it's so powerful that most people are a little scared or don't find it.

just try irfanview, i'm quite happy with it. a friend of mine who shoots hundreds of pics every weekend also uses irfanview.

sizelimit uses the active / top priority toolkit.

thanks, you made me discover some new Photoshop functionality. I'll try to make it work.
