 Hello and welcome today. We're going to be looking at thumbnails in your file manager in this case I'm using PC man FM, which is my preferred file manager But this probably applies to other file managers as well and I have it set up so that it will generate thumbnails and For both images and videos when I'm looking at them in the file browser Sometimes there's issues for example right here. I have one Image that doesn't have a thumbnail and then some here. Let me show you something here real quick I'm gonna open up this one. We're gonna look at this. You can see it's upside down So I'm gonna quickly rotate that go to the next one gonna rotate that so I'm just rotating them but they could be other types of Issues here and when I go to exit I was gonna ask if I want to save those changes and yes It saved them, but it didn't update the thumbnails I can hit f5 to refresh here and you can see this one I think it rotated properly, but these ones rotate and this one's still missing and this has to do with Meta information and the way the thumbnails are embedded in the image They're just not getting updated properly So we are going to force them to update. So we're going to install program sudo app, so let's put this up here sudo apt or aptitude or apt get wherever you use install the name of the program is X E I F Trans so for transform transform, I guess but X ex I F stands for exchangeable image file That's just basically when you take a photo all that information in there About the photo usually about you know what camera was taken what lenses were using your GPS location all that stuff I believe is is part of the Ex I F or the exchangeable image file format So I already had that installed go ahead and saw I'm a devian-based system So again, I'm using apps, but use whatever package manager you use on your distribution and Once it's installed all we have to do is use that we're gonna say it has lots of features, but we're gonna use Ex I F Tran Dash I dash G and the name of the file we want to fix. So I'll just do 4.jpeg here So again, this is in the file browser. I'm in the same folder up here I'm gonna run that command and you can see it updated the Thumbnail there for that image if you have a few like I do we are going to just say do it to all them You do all JPEG do that all back to fix all of them this one still is blank but let's just F5 to refresh there and it's seeing it just There was no thumbnail before and then you hit F5 to refresh my browser to tell it to look there And see that there is a thumbnail the other ones update automatically because it already knew there were thumbnails there But that's it. This is there you might have other thumbnails You don't have any thumbnails at all for anything you have to set that up in some cases That's a different tutorial, but if you haven't set up to get thumbnails and you're getting some and not others This is a way to force it to basically update the thumbnail to match the image So these are all rotated the right way and if you're not getting any They're right there because I've had times where I actually edit images and depends on what editor using but I've edited image image images in my shell and The thumbnails didn't update like I made an image black and white but still color in the thumbnail This will force that to update so quick and simple.
