Block greater than 2mb jpeg/png files on network

[timbo343]

is there a way to block jpeg/png files that are over a certain size. For example, we want to disallow students from saving massive image files (more that 2mb each) on the network therefore forcing them to use a resizer program before hand.

I'd be lynched here if I tried that - as our A-level Photography students are often saving MASSIVE JPG's - but I just use a disk quota on their H:\ drives so when it's full it's full - up to them what they want to save in their space....

hmmm, we use quota'ing on the userareas but they look at us blank when we tell them they need to clear some space from their userareas. All this has come from a teacher requesting lightning cables for photography students.

 

I just looking at all the issues that could occur before we allow it.

How are they going to get the images on the network first in order to run the re-sizer programme on them?

[timbo343]

We do it for them, they come to us and we get the image off the phone. We do give them a warning first about accessing the device, turn the view to details and ask for when the photo was taken. Edited November 7, 2017 by timbo343

I'm sorry, your iPhone photography qualification is out of date because we're now on iOS 12.

 

Can't you just buy a few more 8TB hdds, they're not that expensive.

HAHAHA!!!

 

What we minimal budget each department has, they would look at every option possible before spending money.

[mavhc]

Which means the school is running things in a very inefficient way, they're wasting teacher time, which is super expensive.

Every time a student wants a photo off their phone they have to come to IT Support???

Its the same here. No USB access for students. Just too risky! Plus we don't let pupils have their phones in school, so it is a rare thing anyway.

Same here. Our photography students are consuming 50gb average per student and it was becoming a huge problem. Last year I implemented tougher disk quotas of 10gb per student. Each one of the students has a 1tb one drive account which hardly anyone uses. So I educated the staff to get their student to upload all their photos in to one drive and only download the photos they are looking to use.

To date it is working well

Yep!! had no issues with that for years and prevents userareas been massive as students don't understand the size of photos or videos for that matter and no one wants to teach them!

 

Like i say, they all complain and don't do anything about it when their userarea is full, they all demand more storage. Might as well manage what goes into the userarea first rather than dealing with massive powerpoint/publisher files!

I was going to try that, but our lot might download them all.

What's the risk for USB?

 

Obviously there's a balance to be had between cost of storage and time to manage it, but it's only going to get larger in the future, so you might as well start implementing systems now, auto archive, auto resize, tiered storage etc etc

[dapaulio]

The quota will prevent that

We resize all images as a policy, its pretty easy to do and you loose no quality really from 8mb down to 2mb.

[atcoates]

We have cheap and cheerful buffalo terastation that we use for student video projects and all media files. They are getting long in the tooth now so slowly replacing with synology boxes. We only have supervised devices in school and they use an app called file explorer if uploading from an Ipad or it's just another mapped drive on a pc.

Hi Zag, how do you implement this? Do you mean via a group policy? Would love to know!

[pete]

You've a few options:

 

1) Provision more storage

2) Profile your storage so you can work out your yearly churn, projected increase from (more?) photography students and see if it'll fit.

2a) If it's an option, turn on deduplication.

3) Spend student, teacher and IT time resizing photos

 

We don't use quotas here as it balances out - for every 50GB photography student, I've got 50 other students who barely break 500MB.

hehe I meant as a ICT policy

Ahh .. for a moment there, I thought all my Christmases might have come at once! Magically resizing image files would be in the Top 3 of my Wish List ... probably even sitting at Number 1!! Currently I do this every so often by just searching the server for *.jpg and then using the Image Resizer tool to shrink them ... and then sitting gleefully as I watch the free space on the server gradually increase by GBs at a time!!

 

Thanks for the link to your blog - I will give it a read.

Why don't you use Fast Stone Image Resizer. It works with folders so you can drag the folder into the application and it will resize all images it finds including images in subfolders.

and you do this without first warning the users?

[zag]

Its a policy in our school, so no warning needed. Been doing it 10 years+ now and never had a single complaint.

 

It all depends on how much you reduce the quality and size of course.

[BlueSkies]

Yes, the users know that all .jpg files should be resized (bur rarely do they remember to do it themselves!) - so every term or so, I kindly do it for them!

That sounds great - I'm off to go and get myself a copy of that! Thanks!
