Transparent Image

I have an image, its got a white b/ground, i want it black!
The layer is part locked, i can't unlock it!
How do i get the image transparent please ?

It sounds like it is in Indexed colour mode at the moment (GIF) change the colour space to RGB first. Duplicate your newly converted layer. Depending on the picture make a selection and replace colour.

Good Answer! Good Answer!....survey Says--- Hermit Is Right! Yay!

I'll try that thanks, hopefully i can manage something, i'v already tried for 3 days lololol
Gods i hate pshop, i don't know nothing about it!!
Guess i should'nt hate it just because i don't know it cryptomaniac
I'm giving it another go, trying to create some sort of a sig at the minute,oh well. i'll learn.
Thanks.i

I have another question regarding a transparent image....

I am working for a school newspaper, and am in the process of creating a masthead. I am trying to get a picture offline, which has a white background. I am trying to get rid of this background, because the background color i am planning to use is not white. How do i do this?

Also, is there a way to manually shrink a picture inside of an image in photoshop, or do i have to use pagemaker every time?

the easiest way to remove a uniformly colored background is to select it with the Magic Wand and press delete, then go to layers>defringe and enter about two pixels.

As for resizing an image, go to Edit>Transform>Scale and grabone of the corner handles move it to resize the image. If you want to resize uniformly hold the shift key, if you want to scale from the center hold the alt key, if you want to do both, hold both keys together. If you are on a MAC I think it is shift and option, but I'm not sure.)

cryptomaniac, i got the black background but, my image has an orange **S**that must remain orange !!
This s is in the centre of the graphic, and of course this is now black as well lololol
How do i get round that ..?
Thanks.

Crypto's method can work, but it'll leave a rather jagged edge. If the masthead has a white background as you said it does (and I mean pure white, if it's not, just adjust the levels so it is), select the entire layer (CTRL+A), create a new alpha channel in the Channels window, paste it in. Now invert the colors (CTRL+I), and then load the alpha channel (CTRL+CLICK the channel) and fill in the resulting selection with a color of your choice in a new layer.

To manually shrink a picture, just use Free Transform (CTRL+T) and a bounding box will surround the resizable area.
