Any Suggestions for CGI Script for Web Slide Slow?

Do you have any suggestions for creating a slideshow for my web site, 6 same-size jpgs that rotate automatically?
I think I prefer a cgi script. However, I've tried two that don't work on Firefox or Safari. One developer tells me that he can see the rotating photos.
I'm also open to software to create this. However, I'd prefer to use html code.
Of course, it must work cross platform.
Any suggestions?

Oh, what a beautiful baby! Is he/she yours?
She is mine. At least that's what the Mrs. tells me!
When you say gif, I am assuming that you mean the
format really must be gif and not jpg. Is that
correct?
Yes, the file is a GIF file. It's actually an animated GIF file, meaning that the images that you see are all frames of animation in a single GIF file. There are a lot of apps out there that can create animated GIFs. I happen to use Adobe ImageReady because that is what is on the hard drive.
Can you give me a hint about the dithering issue? Do
I dither or not dither, that is the question.
This is the major downside of the GIF format. It is a really old format...from back in the CompuServe bulletin board days...maybe older. Anyways, it is my understanding that GIFs can only hold information for 256 colors....any 256 colors, but no more and no less. So now in the days of "millions of colors" jpegs, you can imagine that a 256 color palette is limiting. But if the colors of your images are sufficiently close, its possible that 256 colors makes for perfectly acceptable images across all images. This is the one variable of converting images to GIF that can make it or break it for you. If your image has a pretty broad tonal range...like fleshtones or any other gradient...then 256 colors is going to represent things poorly. Then you will get dithering artifacts which is like averaging errors...colors are close...as close as possible...but not close enough to make a smooth gradation. Anyways, that's my layperson's understanding.
But for some images, it looks just fine.

  • Does anyone have any suggestions for Ad blocking? I'm getting a lot of pop up ads while using Facebook from Safari.

           I'm getting a lot of pop up ads. mostly while using  Facebook. I'm running Safari on a Macbook Pro running Yosemite. Does anyone have any suggestions for an Ad blocker. I don't see anything in the App store.
          I can't swear to it but I don't recall this being a problem pre-Yosemite. I could be wrong. I haven't been real active on Facebook until recently. I see some third party apps out there but am alway wary of non approved software.
         Thanks

    You may have installed the "VSearch" trojan. Remove it as follows.
    Malware is always changing to get around the defenses against it. These instructions are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
    Back up all data before proceeding.
    Step 1
    From the Safari menu bar, select
              Safari ▹ Preferences... ▹ Extensions
    Uninstall any extensions you don't know you need, including any that have the word "Spigot," "Trovi," or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
    Reset the home page and default search engine in all the browsers, if it was changed.
    Step 2
    Triple-click anywhere in the line below on this page to select it:
    /Library/LaunchAgents/com.vsearch.agent.plist
    Right-click or control-click the line and select
              Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item named "com.vsearch.agent.plist" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
    Repeat with each of these lines:
    /Library/LaunchDaemons/com.vsearch.daemon.plist
    /Library/LaunchDaemons/com.vsearch.helper.plist
    Restart the computer and empty the Trash. Then delete the following items in the same way:
    /Library/Application Support/VSearch
    /System/Library/Frameworks/VSearch.framework
    ~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin
    Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
    The problem may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
    This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow.
    You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Internet criminal behind VSearch has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing has not done so, even though it's aware of the problem. This failure of oversight has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

    There seems to be a problem, just now, with the USB 3 ports on the new MBP's supporting eternal USB 3 drives. Some people have no luck at all - can't even recognize the drive - and some are reporting USB 2 speeds (those who drives are recognized). I'd call a dealer such as LaCie or OWC to see if they have USB 3 drives that actually work with MBP's with USB 3 ports. You may have to wait for a software/firmware update.

    Sep 23, 2012 10:08 AM (in response to matracaelcan)
    Hi All,
    I had this problem today myself, and was frustrated repeatedly by the '4002' error.
    I have literally just fixed the issue by doing the following steps:
    1: Go to the 'Store' tab and select 'Turn Off iTunes Match'
    2: Return to the 'Store' tab and select 'Update Genius'
    3: Wait for this to complete succesfully, the return to the 'Store' tab once more and select 'Turn On iTunes Match'.
    4: iTunes Match will now go through the motions and should succeed!
    I hope this helps

    Cannot display the screen of my macbook on TV. OS is Lion 10.7.2. The Macbook is connected to the TV is over HDMI cable.  TV shows only the backgroud picture of the Lion OS and reacts even to mission control. Do you have any suggestions for help ?

    You have the display set in Extended Desktop mode. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse.  http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
    Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.

    Hi Mark
    Was just looking for the answer to this exact question and I just found something that worked for me so don't know if it might be of use to you or you might have already solved your problem!  Basically when I was in iMovie and I clicked to import movies from the computer into iMovie and I found the clip I wanted to import, there are a few options.  I think it asked which Event I wanted to add it to but most importantly it asked me what file size I wanted...I had originally been clicking Large because it advised me to because it reduces the file size...but just on a chance there I selected 'Full - Original' for size and it imported perfectly into iMovie in it's original vertical form!
    Hope this helps!

    Any suggestions for building a home network (in a modest 1600 sq. ft. home) with the following requirements...
    1) Laptop(s) and PC share broadband (cable) internet connection

    A) One laptop runs on Windows XP and has an Intel PRO wireless 2915ABG network connection
    B) PC runs Windows XP Media Center
    I was thinking about the wireless N broadband router 300.  From the experiences of the community, will I be able to achieve my goal?  Beside a PC adapter, is there any other hardware I will need?
    A couple other questions.
    The router will likely be sitting right next to my PC.  Does the PC need to have a wireless adapter or can it be wired from the router to the PC?
    When will the media extender be available?  Will it work with Windows XP?
    Thank you.
    Chris

    I personally might not buy Wireless-N, but the idea of being on the bleeding edge is nice.
    Anyway, whichever router you choose, you should be able to accomplish almost everything you need.
    You'll be able to share your internet amongst all of the computers, and share files between them all. Local firewalls and permission settings on individual computers could potentially pose a problem.
    Sending media to your TV may or may not be possible, depending on what other hardware you have. A router itself would not be able to do that, as a TV doesn't usually have any form of WiFi, but if you had a box connected to it for displaying content on the TV, you could do something like that...
    Wireless speakers are generally a separate wireless system. As far as I know, there is a wireless transmitter that sits next to the amp (or other sound source), and broadcasts the music wirelessly to the speakers. You'd have to make sure the speakers and wireless router are on different channels as to not cause interference.
    Don't know much about the media extender, but highly likely will be compatible with XP.

    My mail will not update and stay current. Its always searching but doesn't do anthing. Any suggestions for ipad3?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on some Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem(s)?
    After testing, reboot as usual (i.e., not in safe mode.)

  • HT1338 My Mac book Pro is running very slow and the rainbow ball is appearing all the time. Any suggestions for clean up??

    My Mac book Pro is running very slow and the rainbow ball is appearing all the time. Any suggestions for clean up?? I have the OS X Lion system.

    As well as what a brody asked :
    - do you need more RAM? (run Activity Monitor and see how much free RAM - green - is available)
    - do you Restart fairly regularly, e.g. at least once a week, to clear out any swap or temporary files?
    - do  you need to do maintenance, e.g. clearing out caches and unused logs, etc?

  • Any suggestions for backing up a macbook?  I think it's a Mac OX X v10.6?

    Do you have any suggestions for backing up. I do not currently have a way to back up my laptop. I read many bad reviews for time machine. Is their a cheaper way to back up laptop (I assume it wouldn't be wireless like time machine)?

    Time Machine works. It's free (except for the external disk you need to store the backup on!).
    You may be confusing Time Machine (the backup program builtin to Leopard and Snow Leopard) with the Time Capsule, an Apple wifi router with a hard drive built in.
    Either way, remember that people only come here when they have problems - so you'll see people complaining about Time Machine not working, because they don't post when things just work.
    I use Time Machine for all my Macs. Works really, really well.
    Additionally, I also use Carbon Copy Cloner (donationware) to make occasional copies of my boot disks.
