Normally, I think, you can open the Symbol selector by clicking any of the boxes that is shown as part of the legend below a file in Table of Contents. However, when I try this for a certain file (a tif raster file) it opens the Color Selector instead of the Symbol Selector. Why do you think this is and is there a way for me to access the Symbol Selector?
I want to access the Symbol Selector in order to put a frame around the whole raster.
I think this page at ESRI answers your question:
To paraphrase, points are 72 units to an inch. So a 100 point symbol should be roughly 1.4 inches. But just like when points are used to describe font sizes, there is some variability in size depending on how the symbol was designed - the same reason a page in 12 point Arial font will contain a different number of characters from the same page in 12 point Times New Roman. Taking a look at the ESRI fonts in an application like MS Word might be a good exercise to see the difference in relative sizes.
Switch to a layout view,
Right click the active data frame (layers by default).
Select the general tab and change the scale.
Mine works even without the layout view.
This all on 10.1 sp2

Images are raster layers, not vector. You cannot apply symbology to a raster, rather you adjust how to display it by modifying color settings.
If you want to display a frame around the raster you will need to create a polygon layer and draw the edge around the boundary of your image. You can then display that polygon outline as the frame around your image.
