im making a website for photographers, some images uploaded are vertical, some are horizontal, when we look at the gallery of the pics i dont want the pics to appear too big on the screen and pull the table all over, or, be too small in their box and get stretched.
what i wanna do is put images on display in a box about 100px in width x height, but let them look natural in shape exactly like my favorite free image site - can anyone tell me how to get the file size and resize the images in proportion irregardless of if they are a vertical or horizontal picture.
im stuck,
if you feel like a proper challenge i also want to create a pop up div function that displays the database entry big version of the image that floats.
or am i pushing my luck ;)
thanx in advance
