Photoshop help

I have the letters in my footer. I am trying to make them bigger for my splash page. I need to know how to do it! They are a scanned photo that was e-mailed to me and i put into my docs.

Thanks

I also need to know how to take a image I already made in PS and make it into 1280x1024,1024x768,and800x600.

Thanks again

Yes I am new to PS by the way!

I am trying to replace the ones on here

With the ones in my footer by the way!

Thanks

in your footer file, merge all the letter layers into 1 layer, but NOT the
background layer. leave it at least 1 layer above. Select all and copy.

Then open your splash file and paste. To resize might be tough, but you
can try using free transform tools.
