The ImageSizer plugin from Lumis is a fantastic plugin and you will get to find that out very shortly. This great plugin will make it easy for you to upload any file, crop it and resize it on the fly in multiple places throughout your whole ExpressionEngine site.

We often use ImageSizer in conjunction with the FF Matrix FieldFrame field type to let users add as many images as they want with captions. Then we pull at the first one and give a link to view the rest in a lightbox gallery. Works great!

But some EE users do not realize that that those pictures they take with their tiny cameras are actually really large files. File size notwithstanding, the pixel dimensions are out of control. Now some lightboxes will scale the image to fit in the visible area, but either way it’s still having to load up images that are way too big for the web.

To cope with this problem, developers had to put instructions on the field: “900px wide max.” Yeah that worked. It will mostly meet with blank stares on that one. And then the question of…”so you’re saying I have to resize all my images before I even upload them? I thought you said this was supposed to be easy.” Sometimes we get so wrapped up in the way we use computers we forget that everyone else is still not so sillfull in using them.
