I created a site and decided that in order to show image thumbnails on list pages I do not downsize images and store them phisicaly on server rather have only one larger (max 800x800px) image file which I read into memory resize it to thumbnail size and write it to the browser with the cfimage tag on the fly.
The pros are that I don't have to store different versions of sizes of the same image just one and I can change my mind anytime and show thumbnails in different sizes than originally planned without generating new thumbnail files and throwing old ones out. The drawbacks can be however that reading the larger files instead of small thumbnails can slow down page loading however I can't see it a real critical issue on my site. But from SEO point of view it seems problematic that as far as I know I can't define alt text to these 'on the fly generated images' and apparently they do not have a filename however these could be useful to get better ranking in search engines. Does anybody use this way of image processing instead of storing thumbnail files on server or it is really not a best practice? Could I have somehow alt text on my images? Any other pros or cons I haven't mentioned? Any oppinion is appreciated. ------------------------------------------ Aron Szanitter -> nyerniakarok.hu ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:311902 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
