Problem In moving 1 image from 1 panel to next and maintain size of original image?

Question

Why is it when i drag one image from the bottom panel over to another picture(solid color) i will only get 50% of the image and not the full image. Same thing when i copy and paste that image over the gray solid colored image also i will get only 50% of the image.  The original image of the cat(full view) is about 24.79%  and picture is 11.733 x 15.644 in size.  the other image (solid color) is at 43.63%  or 6.667 x 8.889". size is in inches. Do i have to resize the images and if so how as i am a stupie in this matter. The images are aligned side by side on the main panel or display.I am trying to place the cat over the gray background image  and with a layer mask delete the present baackground of the cat to uncover the gray of the bottom layer.  Thanks!!

Probably the resolution of each image has a different value. You can check this in Image>resize>image size. The resolution is expressed in px/in.
If you are attempting to place the cat on a plain gray background, try this:
Set your foreground color chip  (lower left) to the shade of gray desired
Open the picture with the cat
Using one of the selection tools (e.g. Selection brush, lasso), select the cat
Place the cat on a separate layer (Layer>new>layer via copy)
Place a blank layer between the background layer and the cat layer
Fill the blank layer with gray ( Edit>fill layer>foreground color)
Use the move tool to position the cat, and resize, if necessary, with the corner handles of the bounding box.
