How many photos can I display on a webpage

I'm using a motion detect security camera, which will upload all its captured photos via FTP, to my hosting service. To view and manage the photos, I created a PHP file which will allow me to either display all the photos or delete them all. This is just being used to make sure my cats are OK when I'm traveling. So the PHP file will simply display each file name, timestamp, and the photo, with maximum screen width, since I'll be viewing on a little i-phone.



My question is, do i need to add code to limit the number of photos on the page it creates? Or can I depend on the browser to be smart enough to just load the part of the page its displaying, discarding what is not visible. I need to know this because if one of the cats decides to roll around the floor for an hour at a time, and I don't get to check if for a full day, it feasible I could have 500+ images.



I guess its not that big a deal to add a maximum image limit in my form that controls the PHP code, but if browsers can automatically handle ridiculous size pages, that's one less thing to deal with



EDIT: after some experimentation I was surprised to find that (a) all my PC based browsers (even a lowly I-8) and mobile devices (including my ancient I-phone-4) had little trouble displaying 1000 images, at about 1024 x 780. BUT... (b) browsing through them (especially on a mobile device) was ridiculously tedious, and had I not been on wiFI, I'd have paid for all that data download. So the bottom line non quantified answer to "how many" on modern devices seems to be "a lot more than you'd ever have time to view".



So in the end I added a bit more to my display form and code, so I could view a reasonable number of images at a time, choose how many photos per/page, sort (forward or reverse) by time stamp, and a few other niceties. Everyone's comments wewre indeed helpful

    The browser will load everything, it will not limit to just the photos that fit. You might want to add some sort of pagination.

    You might also consider something like Infinite Scroll, which will fill the page and then load extras as you keep scrolling. Sounds closer to what you want.

  • This is not a code issue, but a device issue. If you want to load 500+ images, the devices browser will need to be able to render them all. This A) uses a lot of network traffic, and B) uses memory resources to load the page. On a desktop computer, this is less of an issue, yet will create performance issues. On an iPhone, this can create performance issues. The browser might crash or stop responding well... So I suggest you consider how this will effect your target audience and build around what is going to provide a positive experience for the user.

The browser will load everything that's present in the html. So, you will have to limit the number of images uploaded yourself, maybe add a filter so it uploads only one image every 5 minutes.

Quarantine

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy...
