Qee tus neeg siv ntsib teeb meem thaum upload cov duab rau cov chaw sib tham thiab cov chaw sib tham. Nyob rau tib lub sijhawm, tej zaum yuav muaj ntau qhov laj thawj rau qhov tsis txaus ntseeg ntawm rub tawm cov duab.
Qhov laj thawj tseem ceeb rau kev tsis tuaj yeem xa duab yees duab rau tus neeg rau zaub mov yog qhov kev daws teeb meem ntawm cov duab. Ntau lub rooj sib tham tswj kev lag luam siv cov qauv uas tsis pub tso tawm cov avatars loj dua 150x150 pixels. Cov vev xaib sib txuas lus kuj tsis pom zoo xa cov duab loj (20 megapixels lossis ntau dua), vim tias qhov no yuav ua rau muaj qhov yuam kev thaum rub tawm cov duab. Txo cov duab daws teeb meem hauv ib cov duab editor, piv txwv li, mus rau 1920 pixels ntawm txoj kab rov tav (FullHD zoo) thiab sim tso cov duab dua. Qhov laj thawj thib ob rau qhov yuam kev thaum upload duab yog cov ntaub ntawv loj tshaj qhov ntsuas pom zoo. Ntau cov blogs, social networks, portals teeb tsa kev txwv ntawm cov ntawv me - piv txwv li, "tsis pub ntau tshaj 2 MB" lossis "txog 10 MB". Yog tias daim duab no muaj lub cev loj, txo qhov kev daws teeb meem thiab qib theem zoo, hloov cov hom ntawv mus rau JPEG - qhov teeb meem txuas ntxiv cov duab nrawm thiab lawv dhau los ua "sib dua". Qhov thib peb yog vim li cas rau kev tsis tuaj yeem ua duab rau cov chaw yog qhov tsis raug ntxiv (hom ntawv). Txhua zaus yuav tsum hloov kho cov duab ntawv mus rau JPEG (JPG) lossis PNG. Cov no yog ob hom kev tshaj tawm uas xav tau me me qhov chaw xa khoom thiab thauj khoom sai sai yam tsis tau poob zoo. Ntau lub rooj sib tham thiab kev sib tham tsis zoo siab tos txais lossis tsis rub tawm cov duab hauv TIF, GIF, BMP, thiab lwm yam. Txhua yam Vim li no, ua ntej tso duab, txheeb xyuas cov hom duab thiab, yog tias tsim nyog, hloov nws siv Xim lossis lwm daim ntawv thov. Qhov laj thawj thib plaub ntawm kev tsis kam qhib cov duab los tso tawm tuaj yeem tiv thaiv kev ua haujlwm ntawm lub xaib lossis qhov yuam kev hauv kev sau cov ntaub ntawv mus rau lub server. Hauv qhov no, tsis muaj dab tsi yuav tsum ua tab sis tos kom txog thaum qhov xwm txheej raug kho thiab sim xa cov yees duab tom qab ib pliag lossis ib hnub tom ntej. Thiab, thaum kawg, qhov laj thawj thib tsib rau kev ua tsis tau ntawm kev xa duab yog qhov qis tshaj tawm ntawm Is taws nem channel. Tej zaum koj tabtom rub tawm lossis hloov kho qee yam, thiab yog li ntawd lub browser tsuas tsis muaj kev nrawm txaus los hloov cov duab los ntawm lub computer mus rau server. Hauv qhov no, koj yuav tsum txwv txhua downloads lossis txo qhov luaj li cas ntawm daim duab.
