Also a blonde question ;)


Which gives you a larger image - A resolution of 72 pixels/inches or a resolution of 300 pixels/inches?

Thanks

Neither exactly, the image can be whatever size you want regardless of resolution, but the image quality will be different. 300 will give you a greater resolution, i.e. there is more detail in the image - for this reason, 300 will give you better quality of image and is better for making larger images.
 
I kind of figured that Jos. Thank you.

Now for printing neither would give you a larger image to print or would it ?
 
KC,
an image of 900 pixels with print to different sizes depending on which resolution you set for it. 900 total pixels at 300 pixels per inch will give you a 3 inch image that will look good on most printers. Some of the more expensive printers have a preferred density of other values, but 300 is a frequently used rule of thumb.

However, if you talk about the form that pops up if you want to change size of an image, then the pixel density given there is ignored in most other circumstances, and you do not need to change it. There is a separate place to change the actual output pixel density when you hit print.

PPI or DPI makes not difference to image resolution as already stated. It is only relevant to determine the print size/quality.
As an example for say a 1800 x 1200 pixel image, the file size will be the same at 72 DPI as it is at 1000 DPI.
