many uses for galleries
there are many uses for an image thumb to be resized to a fixed width and height when creating various galleries. Because if that gallery or slideshow is within a fixed area, like a header in a website... its best to have control of the size of the thumbs so it doesn't break apart the layout.
for example... the link below is a jquery gallery that i modified with a back end using web assist products:
index.php
there are numerous amounts of galleries that have thumbnails at fixed width and height. Slideshow Pro for example, other flash, and jquery galleries:
jquery example (note that the thumbs are fixed width and height)
slideshow/
this way it can give the web designer/developer more control of layout. I basically can take any gallery flash or javascript and make backend which gives the user the ability to upload any image, and have that image resize to the fixed width and height... and then it will preview in place without breaking apart the layout. Depending on the gallery, some thumnails are proportional, and some are not.
I could just set the IMG tag with attributes of width and height. But sometimes the output isn't a IMG tag on the page ... it could be flash.
so basically i would need that functionality so i create a backend for any gallery, and be able to resize proportional or NOT proportional...
i hope that helped clear things up... thank you!!!
