Sebenzisa izinhlelo zokuhlela noma amathuluzi aku-inthanethi ukuze ususe noma iyiphi imethadatha engadingekile ukuze unciphise isisindo sesithombe sokugcina.

Khumbula ukuthi ukulungiselelwa kwesithombe ngeke kuthuthukise ulwazi lomsebenzisi nokusebenza kwewebhusayithi yakho kuphela, kodwa futhi kuzonciphisa ukusetshenziswa komkhawulokudonsa futhi kuqinisekise ukulayishwa kwekhasi okusheshayo. Faka isicelo lawa macebiso kanye nezinqubo ezingcono kakhulu zokuqinisekisa ukuthi izithombe zakho zisezingeni eliphezulu futhi zihlangabezana nezindinganiso zekhwalithi nokusebenza kahle. Zama izinketho namathuluzi ahlukene ukuze uthole inhlanganisela ephelele esimweni ngasinye!

Kafushane, ukunciphisa isisindo sesithombe kuyinqubo ebalulekile yokuthuthukisa ukugcinwa kwaso nokulayisha kumapulatifomu edijithali ahlukene. Ngamaqhinga namathuluzi ahlukene ashiwo kulesi sihloko, njengokuminyanisa okungalahleki, ukukala kabusha, nokuguqulwa kwefomethi, kungenzeka ukuzuza ukuncipha okuphawulekayo kosayizi wesithombe ngaphandle kokuyekethisa kakhulu ikhwalithi yokubuka. Nokho, kubalulekile ukuqaphela ukuthi isithombe ngasinye sihlukile futhi singase sidinge indlela yomuntu siqu. Ngokuzama amasu ahlukahlukene nezilungiselelo, ungathola ibhalansi elungile phakathi kosayizi nekhwalithi ukuze ifanele izidingo ezithile zephrojekthi ngayinye. Masikhumbule ukuthi ukunciphisa isisindo sezithombe kuyinqubo eqhubekayo enikela ekuthuthukiseni ukusebenza kahle kwezinkundla zedijithali kanye nokuqinisekisa ulwazi olunzulu ngomsebenzisi. Ngalawa mathuluzi nolwazi lobuchwepheshe, sizolungela ukubhekana nezinselele ezivela lapho sisebenza ngezithombe ezinkulu futhi sithole imiphumela engavamile ngokusetshenziswa kahle kwendawo yokugcina.
