I have two images,both of them are clickable. There sizes are both
29x33 images. One of them is positioned at 12,12 how would I get the other image right beside of the first image? I mainly need coordinates.
(E.G. ||)

Thanks Alot!

Well, if the first image is at x=12 , and it's width=29 , then just :

x+width = where the image finishes and should start the other one.

Accordingly to how you grab the image, or the size of it, it may need a +1 or not, why?. Sometimes one forgets that 0 counts, so a 29x33 might be 30x34. But if you took care of that, the no worries.

Hope it helps...

Okay so I add the x coord plus the width and get that, but how do I use that with the second image?

You'll use that x+width value as the x coordinate for the second image, so to paste it right where the first image finishes.

If image is positioned at X and the image is W pixels wide, then the edge of the image must be at X+W. If X+W is the end of the image, naturally thats where you should place the second image.

X+W = X2(second image)

This is simple grade school math here folks.

A slight correction, if you want the second image placed directly beside the first;

X = x coord of first image
W = width of first image
W2 = width of second image

X position of second image = X + (W/2+ + (W2/2)

I assumed the position was the top left corner, not the center.

Either way, using your method the second image would be positioned overlapping the first if it's width was greater than the firsts. This way, the second image is always positioned directly beside the first, with the first's furthest right pixels lining up right to the left of the second's farthest left pixels.

Er... RUCCUS, Phaelex is right. Coordinate (0,0) of a not-offseted-image is it's top left corner, so it's x position + it's width will be the coordinate to position the 2° image.

Further on my stuff at...

Sorry I forgot image positions are in the top left corner, used to using 3D where the position is the centre.
