On any image manipulation tags I've seen, you have to calculate the
proper proportions in order to keep them.
Here's some example code when using BlueDragon's CFIMAGE tag:
<!--- Get the image info using the CFIMAGE tag --->
<CFIMAGE
action="info"
srcfile="#variables.tmpServerDirectory#/#variables.PicName#.#variables.tmpServerFileExt#">
<!--- Set the desired width of the thumbnail to create --->
<CFSET variables.NewImageSize = "110">
<!--- Find out what percentage the size that we want the image to be is
to the size that the image already is --->
<CFSET variables.NewPercentage = Evaluate(variables.NewImageSize /
cfimage.width)>
<CFSET variables.NewPercentage = Round(variables.NewPercentage * 100)>
<!--- now create the thumbnail (in this case... just for GIF images) --->
<CFIMAGE
SRCFILE="#variables.tmpServerDirectory#/#variables.PicName#.#variables.tmpServerFileExt#"
DESTFILE="#variables.tmpServerDirectory#/#variables.PicName#_tn.#variables.tmpServerFileExt#"
ACTION="edit"
TYPE="gif"
WIDTH="#variables.NewPercentage#%"
HEIGHT="#variables.NewPercentage#%"
URIDIRECTORY="NO">
Hope this helps!
