QUICK PIC QUESTION

there should be two things at the side one with a block round a shpe and where the block is see through, select the later. i hope you can see what i mean.

First of all you shouldn't use paint because it runs on so little amount of bits that it automatically compresses your picture to worse quality.

Once you hit the A button for text there's two options down below.  In yellow there's like shapes and shit The top option has a white box and the bottom option is see through. Select the bottom one.  If this is a quality project i'd try to avoid paint if you can just cause of the pixels.  Even Word  is better quality and has more editing options lol.

And I also think if you are using a text box then under preferences there should be like background color, make sure it is none.
