Lil Prob While Making A Sig

hey i have this little problem when am making a sig , sometimes when i want to copy a render to the sig , it just doesnt let me! i dont get an error message or anything , it just doesnt let me , what i do is File > Open thin select the render i wanna copy to my sig , and when i select the move tool and try moving the render to my sig , dunt work ;(
plz help
thx in advance

 

What exactly happens? Maybe its the render itself? or its too big or small?

 

More detail please.

 

mabye the render is so big when you copy it you cannot see it, as it is to the side of the canvas

 

its not about too big or small i have moved huge renders to small sigs before , but while i am holding my left mouse button (after clicking on the render) and pointing it to the sig , i dont see that arrow pic (the cursor turns to something like this:-

and when i release the left mouse button it just doesnt work (lol ps , i mean without the cigarete)
hahahah

 

lol i know this sounds stupid but its the only way i can explain exacly wat happens

 

It's a png/psd right? If not you won't be able to move it. You're gonna have to cut it out of the picture and then move it.

 

set it on a brush tool then hold ctrl and drag it across

 

I've come across this problem too, before trying to move the render go to Image ---> Mode and make sure there is a check mark beside "RGB color".

 

cool thanks alot zigzag8336! i can now move renders to my sigs normally!

 

ive had this problem but then it fixes all by itself like nothing happened its really weird
