I'm trying to make my imported image smaller but every time I drag a corner in it just takes away that part of the image instead of scaling down the size of the image.
this is in indesign
hold down control (or command if you're on a Mac) then drag the corner. Hold down shift to constrain the image proportions.
If you want to see your image's dimensions just click on the centre circle of your graphic and it will select the image dimension. Then you can rescale the image.
As Malcolm said , you can press control or command and drag to drag the image along with the frame as you scale.
You can also use frame fitting option from Object - Frame - Fit content to frame and the image will be scaled to fit to the frame . there are other options too.
Hold Shift to scale proportionately, and hold Alt (option key for mac) to force use of the content's center as the anchor point. Hold both Shift + Alt (option key for mac) to scale proportionately from the content's center.
What happens when you're working in InDesign on Mac OS and the keyboard commands SHIFT+COMMAND suddenly will no longer work to resize an image proportionally? Sometimes with images it will behave as if no keys are being pressed. Then, randomly it behaves normally again. Thoughts?
