 This tag reads an image in JPEG format and removes all information not strictly necessary for it's display.
Many image management softwares and cameras embed in the image files they produce some information about how and when the image was created. This may be useful in some circumstances, but is generally not needed when the files are stored in a server and intent to be sent to browsers over the Net.
The average size of this data varies from 5 to 10k, and can even grow up to 58k, as I personnally found in Photo Shop files!
If you have a bunch of files which contain 5k images (ie Id photos), they will all take more than 50k each, a total of 10 times the normal size!. If you have say 1000 of them, this means a loss of 50 megs on your server disk. If you have 10000 of them, you may be paying your site hosting company for half a Gig for nothing! Many times the price of this tag.
Although most software have a function to remove this information, it is generally hidden some where in the settings and few people actually use it or are even aware of their existence.
This very simple tag then just reads a JPEG file and rewrites a pure image in its simpler possible form.
This tag is compatible for CF 5 and CFMX. |
