FREE ONLINE FTP :: NET2FTP.COM
A free online FTP client you can use to manage and upload things to your site; it's easier to use and has features that many paid installed FTP clients don't have, like the option to upload and extract Zip compressed archives.
FREE ONLINE COLOR SCHEMER :: COLOR SCHEMER ONLINE
A free online color palette generator that I use it sometimes to create my color schemes; it's the free online version of ColorScheme Studio (a paid installed color palette program), but features differences between the paid and free versions are not that many.
FREE ONLINE PALETTE GENERATOR:: CSS-DRIVE IMAGE PALETTE
Another palette generator, useful if you want to get a palette from either an image you have on your computer or an url you came across; just load the image or type an url, and the generator will give you a quite big palette for that image. I use it often when the schemes and colors my color picker and photoshop give me are not satisfying.
FREE ONLINE IMAGE EDITOR :: PIXLR IMAGE EDITOR
A free online image editor; while it's not Photoshop, it's still a very good free online editor for your photos and/or images. It has plenty of features, including layers, and in my opinion it's even better (I tried both) than GIMP - the so-called "best free alternative to Photoshop". Definitely to consider for quick edits to your images.
