so i looked on here and saw that rebooting system usually fixes gthumb and it launches and works until i scroll through my photos then it crashes any idea what i can do?
Please provide your system information as described (below) along with more detail, generally.
I’m sure someone will help when they are able.

System Information
While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly; 
Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:
Suggested inxi command (use either):
inxi -zv8 |
(short-form) |
inxi --filter --verbosity=8 |
(long-form) |
inxi man pages |
(manual) |
Running `inxi` within a `chroot` environment
- Add
--color=0to the long-form command, or… - Change the short-form command to
inxi -zv8c0
Your privacy is respected
Please use the expected pre-formatted text enclosures for all code or command output, according to forum guidelines. 
[MiniHowTo] Present code or command output
Note: Grave accent (or, backtick) characters are used.
For inline code or to show a single command:
- please follow this simple example:
code here.
For multi-line command output:
- place text beween two rows of three (```) backtick characters to form a scrollable text box, or …
- use the </> button in the Compose window to achieve the same result.
The empty row between these rows of backtick characters is where to paste any multi-line command output (such as inxi).
An example of a pre-formatted text enclosure:
What is a Quark?
A. In Physics, an elementary particle and fundamental constituent of matter.
B. A character from the Star Trek: "Deep Space Nine" television series.
C. A soft, creamy, usually unsalted cheese traditional to central Europe.
im new to all this so im a bit confused
Type the command given into the terminal, press Enter – then paste the output of that command into a pre-formatted text enclosure as described (above).
Hopefully, that’s less confusing.
Nonetheless I’ll also add some links to help you become more acquainted with the forum (see below).
Regards.

It is important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem. Please also be prepared to provide output from commands if/when asked.
Simply waiting for others to ask you questions is counter-productive – typically, nobody has a 
at their disposal – and your clear, concise and accurate input is often relied upon in order to help you.
Please help others to make informed suggestions based on information you provide.
